Abstract: The dissipation resulting from the coupling of a system with its environment is commonly
viewed as a foe for quantum technologies. Nonetheless, recent developments at light-matter interfaces
have shown that correlated dissipation can be harnessed into novel dynamical states of matter and
entanglement in many-body quantum systems. In this talk, I will discuss how we have recently capitalized
on this knowledge from quantum optics to set the stage for the — yet uncharted — exploration of
cooperative quantum phenomena in quantum hybrid solid-state platforms [1]. I will first introduce a
comprehensive formalism for the quantum many-body dynamics of an ensemble of solid-state spin
defects interacting via the magnetic field fluctuations of a common solid-state reservoir, and then show
that dissipative correlations can play a relevant role in a realistic experimental setup. Finally, I will
discuss how our findings offer a pathway to novel quantum sensing modalities and schemes for realizing
long-range qubit-qubit coupling.
